Multiple search in vim

I was looking at a log file and needed to highlight multiple search items to make the logs more readable. I got into multiple threads suggesting various cryptic vim commands but I was in no mood to remember them. So, I finally hit <a href="http://www.vim.org/scripts/script.php?script_id=479" target="_blank">this.

<img src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/08/perl-one-liners.jpg" alt="Perl One Liners" align="bottom" />This is the third part of a seven-part article on famous Perl one-liners. In this part I will create various one-liners for calculations. See <a href="http://www.catonmat.net/blog/perl-one-liners-explained-part-one/">part one for introduction of the series.

Famous Perl one-liners is my attempt to create “perl1line.txt” that is similar to “<a href="http://www.catonmat.net/blog/awk-one-liners-explained-part-one/">awk1line.txt” and “<a href="http://www.catonmat.net/blog/sed-one-liners-explained-part-one/">sed1line.txt” that have been so popular among Awk and Sed programmers.

The article on famous Perl one-liners will consist of at least seven parts:

No sound on Fedora 11 Leonidas – resolved.

I have been trying to get the sound working on the F11 install that I had. Searched all the sites and blogs I could find. Nothing seemed to be working.

Finally I did a

alsactl init

and WOW, I have got my sound. Worht a try if you too are having issues with sound.

Access the disk image created by Qemu using guestfish in Fedora.

If you are used to using Qemu for doing some experiments with different distro&#8217;s then you would also understand the problem of having to do ftp/ssh to copy the files from virtual machine to local machine. Also you have to run the machine to do that. How would you like to have a application that can help you copy the files to and from the  image without having to run the VM. That&#8217;s exactly what the guestfish does. How to do it, quick demo here:
